Two kinds of Vector Electronic Map and grid electron map, both electronic map devices include map file memory module, processing mould
Block, display module and control module, map file memory module are handled for storing map vector data or grating map data
It is shown that control module is for controlling by the map datum that module is used to transfer in map file memory module on display module
Processing module is to operations such as map amplification, diminution, translations.Both electronic map devices respectively have advantage and disadvantage, need the whole nation compared with
More advantageous using grating map when detailed map, grating map resource is relatively abundanter on network, need not make arrow again
Measure electronic map.More advantageous using map vector in the electronic map for needing special region, we can be according to specific need
It asks to make Vector Electronic Map.Can realize map vector and grating map electronic map used at the same time at present, be
Different interfaces shows map vector and grating map respectively, it is difficult to generate contrast effect, visual effect is poor；During use
It need to control respectively, it is troublesome in poeration.

Wild difference is small, realizes that seamless connection, map vector easy to use are filled with the electronic map that grating map can alternately display
It sets.
Technical solution is used by the present invention solves above-mentioned the deficiencies in the prior art：
A kind of electronic map device that map vector can be alternately displayed with grating map, it is characterised in that including map vector
Module, grating map module, coordinate transferring, processing module, control module and display module, wherein
The map vector module is for storing map vector data；
The grating map module is for storing grating map data；
The longitude and latitude that the coordinate transferring is used to complete grating map is additional, and grating map is made to generate longitude and latitude letter
Breath；
The control module is for the map number in control process module calls map vector module or grating map module
According to being handled it and be input to display module and shown；
The processing module matches for map vector and grating map, according to the latitude and longitude information of the two to its position
Set, ratio is adjusted, the central point and field range for so that it is shown are consistent, transfer, handle according to the instruction of control module
Then data input display module and show；
The data that the display module comes for Display processing module transmission.
The invention also includes map distance-measurement module, map distance-measurement module is used to provide ranging tool for map.
Heretofore described processing module is equipped with data update interface.For with updating map vector module and grid
Map datum in module.
The present invention can be transferred by control module input signal, processing module, handle map vector in use
Related data in module or grating map module, realizes the function of multiplexing；The relevant data of the two can also be transferred simultaneously, according to
Latitude and longitude information is adjusted its position, ratio, and the central point and field range for so that it is shown are consistent, according to control module
Instruction be switched fast the display interfaces of two kinds of maps, visual field difference is small, realizes seamless connection, generates stronger contrast effect,
It is easy to use.
